A 20-cm diameter pipe conveys water with a kinematic viscosity of 1×10-6 m2/s. Determine the velocity of water in the pipe to ensure dynamic similarity with an oil flow of a kinematic viscosity of 1×10-5 m2/s flowing with a velocity of 1.5 m/s through the same pipe.

The answer will be d. reflects light because it cant be all the others because light cant be other things other than light

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
